ORCHARD-HEATER.

Specification of Letters Patent. Patented Nov. 14, 1911i.

Application led January 14, 1911. Serial No. 602,628.

in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings', and to the charac-- ters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in orchard heaters, my object being to provide a device ofthis class which shall be exceedingly simple in construction and -therefore economical in cost, and which shall eiiciently perform the required function.

In my improvement I employ a sort of chimney centrally vlocated and guided, the

said chimney being arranged and constructed for the escape of the products of combustion which enter' from lthe combustion chamber of the liquid fuel receptacle in which the chimney is located. This chimney is closed at the bottom and while perforated above the level of the liquid for the escape of'the products of combustion, the perforations are always above the level of the liquid, the chimney rising andvfalling with the liquid as its level fluctuates in the receptacle. As illustrated in the drawing the top of the liquid fuel receptacle is provided with an inwardly projecting flange forming a guide-for the chimneyas it rises and' falls. This flange is perforated to allow the air to enter ,freely for purposes of coinbustion. The air entering these perforations passes into the combustion chamber surrounding the chimney and forms with the oil or other liquid fuel, a combustible mix- I struction, I will proceed to describe the same in detail, reference being made to the ac- This chimney by virtue of theper` companying drawing in which .is illustrated an embodiment thereof.

In this drawing .Figure 1 is a perspective view of my improved device showing the chimney protruding above the top of the liquid fuel receptacle about half of its length.

Fig. 2 is a. vertical section taken through the device showing the chimney at approximately its downward limit of movement. Fig. 3 is a similar view showing the chimney at approximately its upward limit of movement.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a liquid fuel receptacle which may be of any suitable size and constructed in any desired manner for the reception of liquid fuel 6. To the top of this receptacle'is applied an inwardlyl protruding flange 7 having perforations 8 for the entrance of air. This flange sur- .rounds an opening 9 through which the iioatable chimney 10 protrudes, when the device is in use. A portion of this chimney is provided with perforations 12 which are so arranged that they are all during the.

greater portion of the time below the top of the fuel receptacle, since it is desirable that the portion Vof the chimney above the topof the receptacle shall produce as great a draft as practicable, and it is not desirable to interrupt this draft by perforations,

which would have a tendency to checkY the draft as vwill be readily understood.

The area of the perforations may be regulated as desired and may be determined by experiment. They should, of course, be sufticient for the escape of the products of combustion, and the greater the quantity of fuel consumed the greater should be the area of the perforations in the aggregate. The chimney is closed at the bottom as shown at 13, and while it will be normally slightly submerged in the liquid fuel, it will rise and fall as'the level of the fuel fluctuates, thus maintaining the perforations 12 constantly inthe same relative position to the level of the liquid fuel or the location Vwhere combustion is greatest. By virtue of this fact it becomes practicable to maintain approximately steady and uniform combustion during the entire period of the consumption of the liquid fuel within the receptacle.

flange 7 of the receptacle must of course be From the foregoing description the use and operation of my improved construction will be readily understood.

In Fig. 3 l have illustrated the fuel re- =ceptacle containing a full charge of liquid fuel, that is to say, with this fuel at a level near the top of the receptacle. In this event the ioatable chimney protrudes to its greatest height above the top of the receptacle and some of the perforations 12 are exposed above the top of the latter. ll'owever, as the liquid fuel is consulned the chimney falls therewith and within a comparatively short time the perfor-ations 12 are-all below the top of the liquid fuel receptacle and the portion of the chimney above the top thereof will then produce the maximum draft, whereby the products of combustion are drawn into the chimney through the openings l2 and are thence carried upwardly out of the chimney.

When the device is in use the air circulates downwardly into the receptacle and unites with the liquid fuel, forming a combustible mixture, the combustion taking place in the mixing chamber around the chimney, the flame and products of combustion passing through the perforations, into the chimney and upwardly therein as heretofore explained.

Having thus described my invention, what I claim is:

l. A heater of the character described, comprising a liquid fuel-containing receptacle, a floatable chimney located therein and having perforations near its bottom so arranged that some of them at least are constantly below the top of the fuel receptacle and all of them constantly above the surface of the liquid fuel, the chimney being adapted to move downwardly into the receptacle as the. fuel is consumed to maintain its perlorations in proximity to the location of combustion, thc receptacle being open around the chimney for the entrance of air, for the purpose set forth.

'lhe combination with a liquid fuelcontaining receptacle, of a floatable chimney located therein and adapted to be held at. its upward limit of movement by the liquid fuel, the chimney being open below the top of the fuel receptacle for the escape of the products of combustion, the chimney being adapted to more downwardly as the fuel is consumed to maintain the opening in proximity to the location of combustion, the

said opening being constantly above the sulface of the liquid fuel, the receptacle being equipped with means for guiding the chimney during its vertical movement, and the y fuel receptacle being open at the top around the chimney for the entrance of air for combustion purposes, substantially as described.

43. A heater of the class described, comprising a liquid fuel receptacle, a chimney tloatable thereinand provided with an opening near itsl bottom constantly above the surface of the liquid fuel, the chimney being adapted to move downwardly as the liquid fuel is consumed for maintaining the opening in the chimney in proximity to the location of combustion, the lower extremity of the chimney being closed, and means for supplying air to the said opening.

In testimony whereof I aiix'my signature in presence of two witnesses.
